In an atom, the total number of electrons having quantum numbers
`n = 4,|m_(l)| = 1` and `m_(s) =- (1)/(2)` is

Text Solution

Verified by Experts

The correct Answer is:
3
For `n = 4, l = 0,1,2,3`
Except l = 0, all other .l. values can have `m_l = 1`. Therefore, three orbitals of `n = 4` can have `m_l = 1`. Each of these orbitals can accommodate one electron with `m_s = -1/2`. Thus, the total number of electrons is three.
